"Landmark Laser" is a special term for the description of a show laser system, that is used outdoor to make a certain point visible and exposed from a far distance. Th term "Landmark Laser" is mainly used in Asian countries, in Europe or Americas the term "Sky Laser", "Skylaser" or "Sky beam laser" is more common.
The power needed for Landmark Lasers or Sky Laser heavily depends on the distance the laser should reach with good visibility. Basic Sky Laser applications, e.g. as Sky Lasers for nightclubs, already work from 3W single green (with single beam). For RGB projections a minimum power of 10W RGB is suggested.
However, for most professional applications stronger systems are necessary to create visibilities far over one or two kilometers.
Laserworld offers suitable systems with their RTI NANO RGB, RTI NANO AT and, as super strong solution, the RTI NANO ULTRA Series. But of course the Pure Sapphire and Purelight Systems also create incredible results when pointed to the sky!
We recommend to at least use a strong, single green Pure Micro unit. Our suggestion: PM-4000G. Not only is that units extremely affordable, but it also has enough strength to expose the location to the whole area.
